^bunny san, had not really noticed until you pointed out how thin she was, and it certainly is a matter of concern. I found a comment from a Japanese fan expressingconcern about her loss of weight.

Hope the staff keep an eye on her, and if if necessary, she should cease group activity andundergo medical treatment. Actress Mio Yuki, at about the same age as Narumi, had shown extreme loss of weight,and had to take a medical leave from all acting activity for several months. She has since returned to acting, and Had returned to a normal weight.

Hope Narumi chan is going to be okay, and that she remains healthy and happy...
